After dissecting the Windows 8 Milestone 3 (M3) build that recently leaked to the Web, WindowsNow.com blogger Robert McLaws reported that it includes a Hyper V 3.0 hypervisor. “Apparently it’s (Hyper-V 3.0’s) been in there for quite a while, but between the focus on Consumer features, and the lack of X64 builds leaking out, it’s the first time we’ve seen it,” wrote McLaws.
Including a hypervisor in the client version of Windows opens up a number of interesting possibilities for software developers. For example, it’s possible that Windows 8 could allow some applications to run in a virtual machine using Linux. Or it could give the operating system a way to support applications built for older versions of Windows. It also offers new opportunities for application updates.
